Add-on to Micamlo BP Trial

October 6, 2016 updated by: Boehringer Ingelheim

An Eight-week Randomised Double-blind Study to Compare the Efficacy and Safety of Telmisartan 80 mg and Amlodipine 5 mg and Hydrochlorothiazide 12.5 mg vs. Telmisartan 80 mg and Amlodipine 5 mg in Patients With Hypertension Who Fail to Respond Adequately to Treatment With Telmisartan 80 mg and Amlodipine 5 mg

This is a multi-centre, randomised, double-blind, active-controlled, parallel-group comparative trial to compare the fixed dose combination (FDC) of telmisartan 80 mg +hydrochlorothiazide 12.5 mg and amlodipine 5 mg (T80/A5/H12.5 mg) to telmisartan 80 mg+ amlodipine 5 mg (T80/A5 mg) in blood pressure lowering effect at week 8, the end of the double-blind period in essential hypertensive patients who fail to respond adequately to telmisartan 80 mg+ amlodipine 5 mg. Patients are assigned to one of the two groups after a 6-week open-label run-in period taking T80/A5 mg.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Mean Seated DBP at Trough After 8 Weeks of the Double-blind Period.
Time Frame: baseline and week 8
Change from baseline in mean seated diastolic blood pressure (DBP) at trough after 8 weeks of the double-blind period. After patients had rested in a seated position for approximately 5 minutes, blood pressure was measured 3 times at approximately 2-minute intervals. The mean of the 3 measurements are used as endpoints.
baseline and week 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Mean Seated SBP at Trough After 8 Weeks of the Double-blind Period.
Time Frame: baseline and week 8
Change from baseline in mean seated systolic blood pressure (SBP) at trough after 8 weeks of the double-blind period. After patients had rested in a seated position for approximately 5 minutes, blood pressure was measured 3 times at approximately 2-minute intervals. The mean of the 3 measurements are used as endpoints.
baseline and week 8
The Proportion of Patients With DBP<90 mmHg and SBP<140 mmHg as Seated Blood Pressure at Trough After 8 Weeks of the Double-blind Period
Time Frame: baseline and week 8
Patients with trough seated DBP =>90 mmHg or trough seated SBP >=140 mmHg at baseline were analysed.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
